So this trick is so that you can login with the same username and password on 2 different blogs? Is this correct? From 2 different domains or the same domain?

I really don’t know if this will work, cause I’m kinda a beginner in WP. But I’d try to share only
define(‘CUSTOM_USER_TABLE’, ‘wp_users’);

and not
define(‘CUSTOM_USER_META_TABLE’, ‘wp_usermeta’);

because this is were the capabilities are set, but as I said, I don’t know if that would mess with something and I haven’t tried it yet.

I am using 2.8.6 and am having a similar permissions problem when logging into my secondary blog. These are the pieces of code I have added: in wp-config.php:

define('CUSTOM_CAPABILITIES_PREFIX', 'wp_');

in wp-includes/capabilities.php: replaced:

$this->cap_key = $wpdb->prefix . 'capabilities';

with:

if (defined ('CUSTOM_CAPABILITIES_PREFIX')) {
	$this->cap_key = CUSTOM_CAPABILITIES_PREFIX . 'capabilities';
	}
	else {	$this->cap_key = $wpdb->prefix . 'capabilities';
	}

Does anyone know if this code still works with 2.8.6 or is there another fix? Basically, if I can't get this to work, I am locked out of my admin for my secondary blog.

Ed - I think you forgot to reapply changes to capabilities.php file after the upgrade.

Everything was working perfectly until I upgraded my blogs to WP version 2.8.4 recently. Is anyone out there experiencing similar issue? Better yet, does anyone know how to resolve the issue? I checked the wp-config.php on all of my blogs and they were left intact during the upgrade….

how do i add a second blog to an existing blog and database?
i wanted my main blog for my website news, a second for a current project im doing, and a third for my girlfriend and i to record the times with our dog.

is there a benefit to having the same user name and info from one blog for all of them?
or cant i just install 3 wordpress databases/blogs and make all the logins the same for all the 3?

Well, i have used this for a while now but i have always had the same problem, when a user register at blog A, he get the appropriate roles, but on blog B he´s roll is set to None and i manually have to set user roles!

Any solution to this without using any plugins?
